Gaoligongshan National Nature Reserve

As an international border the reserve serves as the corridor of immigration and melting pot of ethnics and nationalities. The reserve is a home of about 360, 000 people belonging to 16−20 ethnic minorities. There are approximately 16 nationalities belonging to 109 administrative villages, 19 townships and 5 counties. Han, Dai, Lisu, Hui, Bai, Miao, Yi, Zhuong, Nu, Achong, Jingpo, Wa, de'ang, naxi, Derung and Tibetan form the multicultural population.[2] The major livelihood patterns of these inhabitants are agriculture (especially of cash crops such as sugarcane), household industries such as handicrafts, carpentry and logging. There are local organisations such as the Gaoligongshan Farmers’ Biodiversity and Conservation Association, small tourism organisation in Dayutang, and a women’s association in Manghuang that are promoting alternative livelihoods to save the reserve. Ecotourism has developed into one of the major means of subsistence among the inhabitants. The Chinese Ministry of Forestry has allotted 8,550 hectares for tourism development.[1]

There are about 205 species of wild animals classified under 32 families and 10 orders. Hoolock gibbon, Assamese macaque, Phayre's leaf monkey, Indochinese leopard, clouded leopard, marbled cat, red goral, Bengal slow loris, Chinese pangolin, rhesus monkey, stump-tailed macaque, Asian black bear, red panda, river otter, large Indian civet, dwarf musk deer, black musk deer, Gongshan muntjac, and eastern sambar are among the most interesting species.

525 species of birds are recorded, which fall under 58 families and 19 orders. Species under protection are Sclater's monal, golden eagle, cinereous vulture, Mrs. Hume's pheasant, kalij pheasant, satyr tragopan, and silver pheasant.

There are 49 species of fish, and among them are the rare Lu River schizothoracin, Schizothorax myzostomus and Burmese loach.

There are 2,514 native floristic species and 302 varieties in record that belong to 778 genera and 171 families. Some 318 species (12 families) are endemic. Endemic genera include Paragutzlaffia, Metapanax, Notoseris, Syncalathium, Heteropolygonatum, Davidia, Berneuxia, Whytochia, Gaoligongshania, Eurycorymbus, Pterygiella, Dickinsia, and Sinolimprichtia.[5] It is the native home of azaleas (over 800 varieties), arguably the most famous flower in China; the unique species are: white Sim’s azalea, yellow azalea, Photinia glomerata, Rosa biflora, raspberry, Sorbus astateria, Bulbophyllum dulongense, Calanthe dulongensis, Coelogyne gongshanensis, Davidia involucrata. Towards the eastern lower foothill the dominant species are Lithocarpus variolosus, Castanopsis sp., Cyclobalanopsis lamellosa, and several species of Rhododendron. The high mountain slopes (2,800-3,200 m) mostly contain shrubs such as Rosa sp., Rubus sp., Sorbus sp., Gentiana sp., Pedicularis sp., etc. The western slope is mostly disturbed and contains few species of Lithocarpus sp., Acer davidii, Rosa omeiensis, Iris tectorum and Elaeocarpus sp. The mid-elevation wet evergreen forest is mostly rich in epiphytes such as orchids and ferns.[1][6]

In 1983 the southern section of Gaoligong Mountains was declared as Gaoligong Shan Nature Reserve by the Yunnan provincial government. It consisted of Tengchong County and Longyang District of Baoshan Municipality, and Lushui County of Nujiang Lisu Autonomous Prefecture. The conservation was extended in 1986 and nationally recognised as National Nature Reserve. The merged forest reserve became Gaoligongshan National Nature Reserve. In 1992 the World Wildlife Fund (WWF) branded it as Class-A nature reserve with international significance. In 1997 Bio Diversity of National Conditions of China determined it as one of China’s 17 bio-diversity-protecting zones of global importance. In 2000 the reserve was expanded to incorporate Nu River Provincial Nature Reserve around the Nu River valley and the UNESCO declared it as the Man and the Biosphere Programme (World Biosphere Reserve) by UNESCO. World Heritage Convention in 2003 included it as a part of the Three Parallel Rivers of Yunnan Protected Areas, thereby becoming a part of the UNESCO World Heritage Site.[7]

The reserve is divided into three administrative blocks of which two prefecture bureaus are in Baoshan City (Baoshan Administrative Office of Gaoligong Mountain National Nature Reserve) and one in Nujiang Prefecture (Nujiang Administrative Office of Gaoligong Mountain National Nature Reserve). The reserve headquarters is Baihualing, which is known for its exquisite bird watching site.

The reserve is the home of many endangered species of animals. Some important species in the VU category are Hoolock leuconedys, Budorcas taxicolor, Cervus unicolor, Helarctos malayanus, Neofelis nebulosa; and EN category includes Ailurus fulgens, Trachypithecus phayrei, Cuon alpinus. As many as 55 species of plants are also endangered.[8] All the 14 endemic genera are in fact under the IUCN risk category. Out of these 10 taxa are critically endangered, 5 are endangered, 10 are considered vulnerable to extinction, and 107 are still data deficient.[5]

A new species of snub-nosed monkey Rhinopithecus strykeri, which was originally described from northern Burma in 2012,[9] was also discovered in the reserve in 2011. On the morning of 16 October 2011, a forest guard at the reserve took photos of a group of snub-nosed monkeys which were later identified as R. strykery. This made a breaking headline in China especially on the urgent a need of conservation programme.[10] The monkey is a critically threatened species.[11] The new species was heralded as one of the Top 10 New Species 2012 by the International Institute for Species Exploration.[12] In 2012 it was also listed at no 9 of the Top 10 weirdest new species by the Chinese news portal, China.org.cn.[13]

As a habitation of a significant number of human population, the reserve continuously is under threat from human activities. Agriculture remains the leading problem, especially with the heavy use of chemical fertilizers. There is continued expansion of crop, pastures, and farming encroachment grazing into the reserve. Logging of trees for timber and firewood is destroying the natural sustainability. Alternate sources of subsistence and fuels are a serious need to ameliorate the deteriorating situation.[2] Currently, the foremost threat is construction of dams and reservoirs. Chinese government is developing plans to build a series of 13 dams in the Nu River which will undoubtedly adversely affect the ecosystem.[8]
